' TRUNK LOCK.

' tion.

This invention relates to a lock for the side sections of awardrobetrunk type of box having an open top.

Wardrobe trunks are commonly divided longitudinally into two sidesections hingedly connected together, one of the sections having ahinged top. In closing the trunk, the sides are brought together andlocked, then the top. is swung into closed position and locked. Inopening the trunk,

. the top is first swung open-and then the sides are opened. In order toavoid a multiplicity of key operated locks, the sides have heretoforebeen provided with a lock operated by an inside rod, accessible uponopening the top. The top has been provided with a key operated masterlook. Inlocking the sides of such trunks together, it is necessary thatthe parts be brought snugly together, and then the hinged leafsupporting the master lock swung into closed position. This is often alaborious and a diificult job. The objects of my in vention are, first,to provide alockstructure for the'sides, which will engage the sidesbefore they are fully closed and whose parts are so arranged that theymay be used to draw the sides into snugly closed posi tion; second, toprovide means whereby closing of the top draws the sides together andlocks the same in closed position; and third, to provide a structuresuch that opening the top automatically unlocks the sides and will startopening of the trunk.

These objects together with other objects and correspondingaccomplishments are obtained by means of the .embodiments of myinvention illustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary longitudinal section throu 'h a trunk at rightangles to the plane of ture, the trunk being fully closed and locked;Fig. 2 is a fragmentary view of the trigger -portion of the structurewith the top in partially open position during, the operation ofclosing; Fi 3 is a fragmentary view showing the si es partially open andwith ivision showing'the lock strue Applioation flled April 10, 1923.sum a... 632,281."

the latch about to engage the kee r; Fig. 4 1s a sectionthrough thetrunk ta en on the line 02-02 in Flg. 1; Fi 5 is a fragmentary viewinsectionthrougrthe trunk showingthe keeper in'plan; Fig. 6 is'a modifiedform' of trigger shown in elevation; Fig; 7 is a side view of thestructure shown Fig. 6;- and F1 8 isa section as seen on the line y-g oFig.1.

Referring more particularly to Figs. 1 to 5, inclusive, one side of thetrunk having a closed top is indicated by 1. A side 2 is hingedlyconnected thereto and is rovided with an open top 3. Secured to t e top3 is a finger 4. extending downwardly and provided with a laterallyextending pin 5.

Pivotally mounted upon the side 2 by a 1n 6 is a trigger-6 disposedto beengaged y the pin 5. A pawl 7 is pivotally mounted upon trigger 6, andpin 6' limits the swinging of the pawl in a clockwise direction. A link8 is secured to one end of the trigger 6 and to a bell crank lever 9,which is pivotally mounted at 9' upon a late 10 secured to the side 2 ofthe trunk. onnected to the other endof lever 9 is a latch 11 having arounded nose and a hook to engage the keeper 12 which is secured toside 1. The latch is guided by means of a pin 13 fixed to plate 10 andriding in a slot 14 having an upwardly inclined inner end. The keeperhas an abutment 15 disposed to be engaged by the rounded nose on thelatch.

Suppose the parts are in the position the trunk. The top is swung intoopen position. In the opening movement of the top, finger 4 and pin 5are swung upwardly so that the latter engages the pawl 7 The pawl cannotbe moved clockwise upon the trigger 6 and therefore causes the triggerto be'swung in a clockwise direction. This depresses the link 8 andswings the lever 9 into the position shown in Fig. 3. Swinging of thelever causes the latch 11 first to be protracted longitudinally, forcingthe trunk sides apart as shown in Fig. 3 by reason of the latch pressingagainst abutment 15. At the end of the longitudinal movement of thelatch, the pin 13 rides into the inclined end of the slot 14 causing thelatch to be swung so that the hook moves out of the slot in the keeper,thereby unlocking the sides. At the upper end of the movement of thetrigger 6, pin 5 on finger 4: will ride from beneath the pawl 7. Inclosing the .90. shown in Fig. 1-, and it is desired to opentrunk, top 3is brought into closed position- The pawl 6 is disposed in the ath ofpin 5 and the latter may pass it'ias s own in Fig.

2. The pin 5 then enlgages'the trigiger 6 and swin s e latter so t qt.link 8 is rawn upwardly to the position shown in Fig. 1. Lever 9 isswung from the position shown in Fig. 3, firstcausing the latch 11 to beswung upwardly so that the hook engages keeper 12. Thereafter, continuedmovement of the latch due to pressure upon the cover 3 causes the latchto be retracted longitudinally bringing the sides 1 and 2 together. Thepin 5 rests upon the finger 6 holding the latter in its locked positionso that the sides cannot be opened. B locking the cover 3 closed, thesides are a so maintained closed.

Referring particularly to Figs. 6 and 7 a modified form of structure isshown wherein the lock may be operated from a key and not from thecover. A leaf 16 carrying a master lock is hinged to a section securedto a pivot pin 17 Thus, the leaf may be turned to -be in line with itskeeper and then swung into locked position. Pin 17 is pivotally mountedin side 2 and is secured to an arm 18 mounted on the inside .of thetrunk; Link 8 is pivotally secured to arm 18. It is obviousthat byturning leaf 16 the lock for the sides is operated. When the leaf is inposition to be locked the lock for the sides is locked.

While I have disclosed my invention as able mechanical changes beingmade where necessary.
